How should oxygen sensors be serviced to avoid damage and ensure proper installation on 2006 Audi A4?

Catalytic converters have oxygen sensors that may be hard to loosen during cold weather. Turn on the engine a little to prevent the damage. Always be careful with sensors and avoid connection of contaminants to sensors. In upstream sensors, unscrew with a socket and disconnect, with upstream add anti-seize.
